Can Air Filters Ease Asthma and Allergies?

According to the National Heart, Lung and Blood Institute, over 25 million people in the United States suffer from asthma. When asthma attacks occur, the chest tightens and the sufferer has a shortness of breath or wheeze. It can happen unexpectedly, and may be triggered by specific things in your everyday environment, or even allergies.

Pollutants and allergens such as pollen, ragweed, mold, pet dander and cigarette smoke are common triggers of both asthma and allergies. Therefore, it is essential to clear the home of as many impurities in the air as possible. While there are many methods of doing this, most people already have a tool to help—their furnace. Discover how your heating and cooling system can relieve your asthma symptoms.

  • Air Filters Make the Difference
    The purpose of a filter in the HVAC unit is to maintain your indoor quality by capturing dust and other pollutants. Furnace filters are essential for asthma and allergies, because the filter captures the pollen, mold, pet dander and common airborne allergens—keeping it out of the air. Cleaner indoor air can make a big difference in how easy it is to breathe indoors for those with respiratory conditions. This is why it is important to change your air filters frequently.
  • What Filter Should You Use?
    Choosing an air filter to help prevent asthma symptoms requires research because each filter has a rating called a MERV. First, you want to use a filter that fits your system. Getting a precise measurement and MERV rating is important, so the filter can function efficiently. The higher the rating, the more efficient the filter is at capturing allergens and airborne pollutants. Consider a filter with a MERV rating of 11 or 13 for the best results.

As you can see, it is vital that you choose the right furnace filter and change them regularly. Not only will doing this keep the air that flows through your home cleaner and healthier for you and your family, but it may also reduce heating and cooling costs too.
